Why not put the extra cash saved on the motherboard towards something like a bigger SSD, better graphics card, or more ram?
Unless your willing to push yourself to a 3930k or something, what's the point in spending so much more on the motherboard? buy a better graphics card, or bigger SSD. Youll be happier in the end. Especially with haswell. Haswell ISN'T any better of an overclocker than previous gens.
Personally, if it were me, and I wanted best bang for buck, I might actually stick with ivy bridge. Haswell just isn't that amazing, for price vs performance anyway. That said I got an Asus Z87 pro and 4770K. Couldn't be happier.
The best way to decide whether or not its worth it, is to simply ask yourself what features the better motherboards have you are going to use (that the lower end ones don't have). If you cant answer that, then you are probably wasting your money.
But, honestly, if your dead set on spending more on the motherboard, then it's pretty simple, nothing said here will likely stop you! So have at it!
